FREDERICK B. WALTER, OF CHICAGO, ILLII' HAIR-CUTTING INSTRUMENT.

Specification of Letters Patent.

Patenten Dec. 7, tooo.

Application filed January 31, 1908. Serial No. 413,653.

To all whom fit may concern:

Be it known that I, FREDERICK B. Wai/rau, a citizen ot' the United States, residing at Chicago, in the eounty of (look and State of Illinois, have invented 'certain new and useful Improvements in Hair-Cutting Instruments; and l do hereby declare the following to be a full, clear, and exact description otl Ythe invention, sueh as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hair cutting instruments and has for its object the provision oi' an instrument of sueh character that by its use, the use of scissors and hair clippers may be avoided, the instrument being so constructed and of such character that the hair cutting operation may be performed in mueh less time and in a more satisfactory manner than is possible in the use ot scissors and clippers. The instrument is, in ei'eet, a hair razor.

llroadly stated, the instrument eomprises a flat body provided along its lengthwise edges with teeth and a blade supported upoxr the body in such a manner as to be adjust- \able to and from the body, the blade having two 'utting edges each ot' which is parallel with respect. to the point ot' one set o'f teeth. By providing for this adjustment, the instrument may be adapted to eut a persons hairl to any desired length and it is in this feature that the principal novelty lies.

In the accompanying drawings, Figure l is a plan view ot' the instrument, Fig. 2 is an edge view, and, Fig. 3 is a transverse seetion. Fig. -t is a detail view showing the blade adjusted to lie in spaced relation to the comb. i

As shown in the drawings, the instrument comprises a flat body Which may be formed of metal, hard rubber, eelluloid, bone or any other suitable. material from which combs are usually made and eomprises a handle 5 and a working portion (S along the longitudinal edges of which are formed series ot teeth '7. A threaded stud 8 is located midway of the Working portion 6 of the body and this stud, When the body is made of metal, is preferably formed integral therewith and when the body is made of other material, is setor fixed into the same. The.

stud mentioned labove nroieetsat right angles from the working portion of the body and a blade 9 is formed with a central threaded aperture l() and is engaged upon the stud and prior to use ot'the instrument is rotated until brought to the proper elistanee from the said working portion ot the body of the instrument and with its eulting edges ll in parallel relation to the points otl the teeth 7 after which a ttnunb jam nut 12 which is also engaged upon the stud, is screwed down upon the blade and holds itin adjusted position.

From the foregoing description of my invention it will be seen that I have provided an instrument for the purpose stated which may be more advantageously used' than similar instruments now employed and that the adjustability ot the blade with respect to the working portion ot' the body of the device, permits ot' the useneutting a persons hair to the proper length. It n ill t'urther be understood that the instrun'ient may be used in either hand and that instead ot' the upstrokes necessary with scissors and clippers, a downward stroke is all that is required in the use of my instrument embodied in my invention.

lhat is claimed, is f l. An instrument of the class described comprising-. body provided with teeth, a stud formed upon the body, a blade, means `whereby the blade'may assume ditlerent positions upon the stud to and from the body with its cutting edge normally parallel-with respect' to the points ot the teeth, and other means to hold said blade. in adjusted position on the stud.

2. An instrument ot thel class described comprising a body provided with teeth, a threaded stud formed upon the body, a blade provided with a threaded aperture engaged upon the stud, said blade being adjustable to or from the body by rotation upon thestud. and a lock nut held upon said stud to secure said blade in adjusted position thereon.

In testimony whereof, I laiix my signature, in presence of two witnesses.
